Beard Hygiene Exposed: What Science Really Says About Your Facial Hair!

For some, beards represent the epitome of rugged attractiveness and masculine pride. Yet for others, beards are simply unappealing—and their aversion might not be unfounded.

Historically, facial hair has been viewed with a degree of skepticism, and for good reason. Our skin hosts a vast array of microbes, and beards provide an ideal environment for these organisms: warm, moist, and often filled with remnants of food, oils, and dead skin cells. According to Nature Reviews Microbiology, the microbial communities on our skin are influenced by factors like pH, temperature, and moisture levels—all of which are altered significantly by facial hair.

A study that compared the cleanliness of men’s beards and dog fur in MRI scanners revealed that beards contained more microbes—and more harmful types—than the fur of dogs. The study’s findings led to the conclusion that sharing an MRI with a dog poses no human health risks, hinting at a less flattering view of bearded men.

The Unsettling Truth About Beards

The controversy over beards has been particularly heated in medical settings for many years. Some studies indicate that bearded healthcare professionals may harbor more bacteria overall compared to those who are clean-shaven. However, the issue isn’t black and white. Research has shown that bearded doctors may be less likely to carry Staphylococcus aureus, a common culprit behind serious hospital infections. Importantly, these studies also found no increase in infection rates among patients when bearded doctors wore surgical masks.

Yet, the potential health risks associated with poorly maintained beards are real. For example, neglected beards can lead to skin problems such as impetigo, commonly caused by S. aureus bacteria. Additionally, there have been instances where pubic lice were discovered in facial hair, typically under conditions of inadequate hygiene or close contact with an infected individual.

Ultimately, the cleanliness of a beard largely depends on its owner. Experts state, “Accumulations of sebum, dead skin, food particles, and pollutants can irritate the skin and foster growth of fungi and bacteria.” This is why dermatologists urge regular beard washing, moisturizing, trimming, and combing to remove debris.

While beards aren’t inherently grubby, they can become havens for microbes if not properly cared for. Think of your beard not as a storage area for leftovers, but as something deserving of regular upkeep. Clean it thoroughly, maintain it properly, and honor your facial hair. Otherwise, you might just find your beard is less appealing than a dog’s rear—and certainly not as endearing.
